What exactly is the Internet?
The best way to think of the Internet, or Net as it is often called, is as a vast global network
of networks connecting computers across the world. These networks range from government
departments and industrial and educational communication systems down to the personal online
service providers such as CompuServe,Delphi.
At present, more than 476 million people use the Internet and over 100 million computers
worldwide are linked in. Monthly the size of network increases on 7-10%. People use the Net for
transferring data, playing games, socializing with other computer users, and sending e-mail. The
network of Internet, that served first to the research and educational groups, becomes all more
popular in business communities.
How did it begin?
The Net was dreamt up in the late 1960s by the US Defense Department’s Advanced
Research Projects Agency which decided that in the event of a nuclear attack, it needed a means
by which messages could be sent and received even if phone lines were inoperative. In 1969,
there was a network of just four mainframe computers. By 1972 the number had risen to 40.
About this time the idea of the electronic mailbox was born as users looked for a way of talking
to each other electronically. By 1984 when the resources of the network were made available to
academics, the Internet began to develop into the form we know it today.
E-mail is much faster than traditional or snail mail because once the message is
typed out, it arrives in the electronic mailbox of the recipient within minutes or seconds.
Anything that can be digitized – pictures, sound, video – can be sent, retrieved, and
printed at the other end. This is efficient convenient, and saves trees!
Functioning of e-mail is built on principle client-server. For an exchange of
letters with the mail server, you need the special program-client.General
functions of the program - the client are preparation of text, sending of letter ,
preparation of answer.
This is perhaps the fastest growing area of the Internet as more and more people
put their own information pages on line. One thing that computers do very well is
process vast amounts of information very fast, so, by specifying a key search around the
Net until it finds some matchers. These information sites are usually stored on big
computers that exist all over the world. The beauty of the Net is that you can access all
of them from your home, using your own PC.
The World Wide Web, usually referred to as WWW or 3W,is a vast network of
information databases that feature text, visuals, sound, and even video clips. On the
WWW you can do such things as go on a tour of a museum or art exhibition, see the
latest images from outer space, go shopping, and get travel information on hotels and
holidays. You can even view a hotel’s facilities before deciding to book.
Usenet is a collection of newsgroups covering any topic. Newsgroup allow users
to participate in dialogues and conversations by subscribing free of charge. Each
newsgroup consists of messages and information posted by other users. There are more
than 10,000 newsgroups and they are popular with universities and businesses.
Telnet programmes allow you to see your personal computer to access a powerful
mainframe computer. If you are an academic or just have a lot of number- crunching to
do it can be very useful and cost- effective. You'll be able to access programs and
services on a remote computer as if you were sitting in front of his monitor.
